Installation

ME-RC50/ME-ARC50

– Full feature remotes with backlit LCD

display and LED indicators for inverter and charger status. Provide

full menu access for easy selection and adjustment; come with a

50’ cable. The ME-RC50 and ME-ARC50 are used for many inverter

models and have additional features that are not functional with the

MMSA1012 inverter/charger.

Do I need an optional ME-RC or ME-ARC remote?

An optional ME-RC50 or ME-ARC remote control provides additional

settings not provided by the DIP switch settings. Review the

following information and the adjustable settings in the remote

owner’s manual to determine if the inverter’s (DIP switch) default

settings (per Table 4-3) are adequate for your system needs.

Search Watts:

This setting allows you to enable the power-saving

Search mode circuitry and to adjust the power level at which the

inverter will “wake up” and start inverting. This function is adjusted

to 5W (“wakes up” and inverts if loads exceed 5 watts) on the MMSA

inverter/charger.

LBCO:

This setting determines when the inverter turns off based on

low battery voltage (inverter turns off automatically once battery

voltage remains below this setting for

more than

one minute). This

protects the batteries from over-discharge and the AC loads from

unregulated power (brown-outs).

Battery AmpHrs:

This setting allows the user to input the battery

bank size in amp hours (AHs), which provides information to the

charger on how long to charge the batteries in the Absorb charging

stage.

Battery Type:

Sets the type of batteries being used in the system

which provides information to the charger to determine what voltage

level to charge the batteries.

Charge Rate:

This setting uses a percentage of the charger’s

maximum output to determine the output charge rate. This setting

can be used to limit the amount of current that the charger can use

(leaving more current available to power loads); or, to ensure small

battery banks are not overheated because of a charge rate that is

too high.

VAC Dropout:

Sets the minimum AC voltage that can be present

on the AC input before the unit transfers from Standby mode to

Invert mode. This protects the AC loads from utility outages and

brown-outs.
